One way of looking at the question of how many to make is this:

decide how much money you want to make. actually pick a number.

figure out how many whoopies you have to bake to get that money, including samples, cost of materials, etc.

make that number of whoopies

go sell them

if you sell out, you made your target, you reached your goal, CONGRATULATIONS!

if you don't sell out, evaluate what happened. did you overestimate how many you could sell? did you pick too high a number? was it close enough to be within your margin of error? was your price too high? etc.

....

Of course, you want to make as much money as possible. but there's also something to be said for just reaching your goals. when you eat, you just eat a sufficiency, not all the food you can hold, right? enough is enough. well, anyhow, until you have more empirical data about your sales, picking a goal seems to me like a useful approach.

*****

regarding the samples.

since you say your whoopies won't last a week until the next sale, can you sell them elsewhere before they expire? will you be able to eat them up at home/neighbors/friends between the end of the market and the expiry of the whoopie? what about sample *size* whoopies that could be sold in a sixpack of tinys or given away as individual "samples"?

I'm just thinking out loud here.

GOOD LUCK, THEY LOOK DELICIOUS!!
